Candidates' Children Hit The Campaign Trail (PHOTOS)

As the 2012 presidential campaign heats up, some candidates are turning to a secret weapon on the campaign trail: their kids. While most candidates bring out their families at events and invite their children to make speeches on the trail, many campaign kids are also stepping into key roles in their parents' presidential bids.

Jon Huntsman's three oldest daughters have taken over the spotlight -- arguably getting even more press than Huntsman does -- and the Romney brothers have fundraised while their Dad courts voters in early primary states.

Here's a look at political offspring who have worked the campaign trail:

Former Utah Governor Jon Huntsman's three oldest daughters made a name for themselves by tweeting from the campaign trail using the <a href="http://twitter.com/Jon2012girls" target="_hplink">@jon2012girls</a> account in 2012. Liddy, Mary Anne and Abby, all in their mid-twenties, have steadily gained followers since the campaign.
Huntsman's daughters have also done a slew of television interviews, and have produced a few campaign videos of their own--most notably, <a href="http://www.youtube.com/watch?v=iOYVB2hc0HA" target="_hplink">a parody</a> of Herman Cain's infamous smoking ad.
